ATN Mars 4 384 4.5-18x

• 384x288 thermal sensor: The sensor gives this scope enough detail for dependable target detection while keeping the image processing load manageable, which helps deliver a smooth view for scanning and shot placement in changing field conditions.
• 4.5-18x magnification range: The wide zoom span covers both observation and more deliberate shooting, letting the scope work across open ground where extra image scale helps confirm targets before taking a shot.
• 60 Hz refresh rate: A faster refresh rate keeps movement looking more natural when tracking animals or scanning from awkward positions, reducing the lag that can make thermal aiming less intuitive.
• Smart HD recording and Wi-Fi connectivity: Built-in recording and wireless streaming make it easier to save footage, review shots, and share the live view with a companion without adding external accessories.
• 18-hour internal battery life: Long runtime reduces the need to manage spare power during extended hunts or night sessions, so the scope stays ready for longer periods in the field.

About the ATN Mars 4 Series

ATN Mars 4 is the company’s fourth-generation Smart HD thermal riflescope series, built for hunters and shooters who want a thermal optic that combines target detection, digital tools, and onboard recording in one unit. The series uses the Obsidian IV dual-core thermal processor and was offered in multiple configurations, with different sensor resolutions, objective sizes, and magnification ranges to suit anything from shorter-range woodland use to more open-country observation and shooting.

A defining trait of the series is that it brings together thermal imaging with practical field functions rather than treating the scope as a simple viewer. Shared Mars 4 features include simultaneous video recording and Wi-Fi streaming, a ballistic calculator, one-shot zeroing, Recoil Activated Video, and digital tools such as a smart rangefinder, electronic compass, and profile manager. Depending on the model, the series uses 384x288 or 640x480 sensors at 60 Hz, giving users a choice between a more accessible thermal setup and higher-resolution options. Across the range, the design focuses on combining thermal detection capability with familiar riflescope handling for hunting optics and night shooting applications.

About the ATN Mars 4 384 4.5-18x

The ATN Mars 4 384 4.5-18x is configured for shooters who need more native image scale than entry-level thermal scopes provide. Its 4.5-18x magnification and 50.00 mm objective lens make it particularly suited to open terrain, field edges, and longer observation lines where identifying heat signatures at distance matters as much as simply detecting them. With a stated 1800.00 m detection range, this model is built to pick up heat sources well beyond normal shooting distances, giving the user more time to assess movement and direction before engaging.

The thermal core uses a 384x288 sensor with 60.00 Hz refresh rate and a 60.00 mK NETD. In practice, that means the scope is designed to maintain a fluid image while tracking moving targets, while the sensor sensitivity supports usable thermal contrast in uneven weather and mixed backgrounds. The 1280x720 Micro - HD display presents the digital image at a comfortable viewing resolution, and the multi-reticle system gives the shooter flexibility to choose a reticle style that better matches the rifle setup and intended use.

This model also reflects the Smart HD approach that defines the Mars 4 line. Video recording, image capture, and video output are built in, while WiFi connectivity supports wireless functions without extra modules. The 90.00 mm eye relief helps maintain a safer and more forgiving shooting position on heavier-recoiling rifles, and the aluminium housing, fogproof and waterproof construction, and 18.00 h internal Li-ion battery support longer use in demanding night-hunting conditions.

About ATN

ATN was founded in 1995 in Silicon Valley, California, and focuses on night-vision, thermal-imaging, and digital day-and-night optics. The company later established its headquarters in Doral, Florida, and its product range spans thermal devices, digital night vision, and traditional image-intensifier systems. That specialization is important in products like the Mars 4, because ATN’s development has long centered on combining imaging hardware with onboard digital functions rather than treating optics and electronics as separate systems.

Within the digital-optics category, ATN is known for its Smart HD and 4K-resolution systems. It introduced the X-Sight II HD series in 2015 and, in 2018, brought in products based on its Obsidian 4 Dual Core platform, which helped define many of its connected and recording-capable optics. This background makes ATN particularly relevant in thermal and night-hunting equipment, where features such as onboard video, wireless connectivity, and digital ballistic tools are part of the core design rather than add-on extras.
